From Website to Mobile App: How I Used Capacitor to Build an Android App

Did you know you can turn your existing website into a native Android app without rewriting a single line of code?

What is Capacitor?

Capacitor is an open-source framework by Ionic that wraps your web app into a native mobile shell. It supports Android, iOS, and desktop.

Requirements

• Node.js v22+
• Android Studio
• Your existing web project

Step 1 — Install Capacitor

npm install @capacitor/core @capacitor/cli @capacitor/android
npx cap init

Step 2 — Copy Your Web Files

Copy your HTML, CSS and JS files into the www folder.

Step 3 — Add Android Platform

npx cap add android
npx cap sync android

Step 4 — Build the APK

Open Android Studio:
Then: Build → Generate Signed Bundle / APK

Result

In less than an hour I had a working Android app from my existing website nexdam.it — no React Native, no Flutter needed.

The same approach works for desktop apps using Electron.
